新课程改革视野中好课的总体要求应该体现在建构性、生成性和多元性的统一。要上好一堂课,必须根据不同的教学目标和不同的学习阶段针对不同的学习对象选择合理可行的教学方法和教学手段,安排好课堂教学步骤。教学步骤一般可分为复习旧知识,告知教学目标,呈现新知识和促进新知识的理解。 The overall requirements for good lessons in the new curriculum reform vision should be reflected in the unity of constructiveness, genesis and plurality. To have a good class, we must choose reasonable and feasible teaching methods and teaching methods for different learning objects according to different teaching objectives and different stages of learning, and arrange classroom teaching steps. Teaching steps can generally be divided into reviewing old knowledge, teaching objectives, presenting new knowledge and promoting understanding of new knowledge.
